Symmetrical and periodic nature of trig functions (radians)

How long is one cycle of the graph?

State the $x$x values for which $\sin x=0$sinx=0, from $x=0$x=0 to $x=2\pi$x=2π inclusive.

State the first $x$x value for which $\sin x=0.5$sinx=0.5

Using the symmetry of the graph, for what other value of $x$x shown on the graph does $\sin x=0.5$sinx=0.5?

Using the symmetry of the graph, for what values of $x$x does $\sin x=-0.5$sinx=−0.5?
